Discussion on TL4657

This grassy triangle at the corner of Tenison and Lyndewode Roads was once home to a cannon, a relic from the Boer War, and was known as Cannon's Green.

The gun was removed in 1940 for war scrap. BBC Radiio Cambridgeshire reported on 5 January 2017 that a campaign had been set up to replace it with a replica (or even to restore the original if it had managed to escape melting down).
